The Gunners won seven consecutive Women's Premier League titles from 2004 and finished top in the first two seasons of the WSL.

But these two sides usurped the Londoners to battle it out at the top of table all season, culminating in a winner-takes-all encounter at the Halton Stadium.

The triumph completes a remarkable turnaround for Liverpool, who finished bottom of the table for the last two seasons.

But after huge investment from the club's American owners, manager Matt Beard overhauled the squad for the 14-game league season and saw his side lose just twice.

The pre-match scenario invited comparisons with the dramatic finale to the men's First Division title in 1989, when George Graham's Arsenal travelled to Liverpool needing a 2-0 win, which they famously sealed with Michael Thomas's last-minute goal.

Any winning scoreline would have done for Bristol, but the hosts made the stronger start and the influential Rolser curled one effort over before being denied by a superb save from goalkeeper Siobhan Chamberlain.

It was no surprise when the German forward was involved in the opening goal, drawing a foul after twisting and turning in the penalty area, with Fors lashing the spot-kick past Chamberlain.

Bristol are positive story - Sampson

Bristol created a rare chance moments later when Laura del Rio tried to lob Rachael Laws, but although the Liverpool keeper was beaten the Spaniard's shot rolled inches wide.

The visitors have made a habit of coming from behind this season, but they struggled to break down Liverpool's defence as the Reds sat back after the break.

It was the home side who had the better chances on the counter-attack, with Amanda da Costa sending a simple header over the bar after finding herself unmarked 10 yards out.

The decisive second goal came 10 minutes from time when Natasha Dowie laid off a free-kick to Omarsdottir, who took a touch before rifling past Chamberlain from 15 yards.

In Sunday's other matches, Arsenal recorded a 2-1 victory at Everton to cement their third-place finish, Lincoln won 2-0 at Chelsea while Birmingham eased to a 3-0 success against Doncaster.
